用X-射线衍射法确定了在20~400℃温度范围内，甲酸锶的三种多态物种α，β和δ以及甲酸钙的四种多态物种α，β，γ和δ的存在。给出了所有这些变种的晶格，并精确地说明了它们存在的温度范围。指出了水蒸气痕迹在某些多晶型转变中的重要作用。
The existence, in the temperature range 20–400°C, of three polymorphic species α, β, and δ of strontium formate, and of four polymorphic species α, β, γ, and δ of calcium formate is established by the means of X-ray diffraction. Crystal lattices of all these varieties are given, and the temperature ranges for their existence have been precisely stated. The importance of the role played by water vapor traces on some polymorphic transitions is pointed out.
